Thanks again, Payne, I have heard from a moderator. They said they cannot force a social group to be private. IMO, that would be a good option for people who wish to speak explicitly on any topic, instead of putting triggering words (for example, blatantly sexual or religious) in the thread title, or even in the post content. Unless you purposely enroll in and enter that social group, you would not be subjected to such material. Not censoring, just separating. You CHOOSE.
I was advised to PM Doc John. But since it looks like I'm the only one who has the objection (and the crummy phone), I'll just stuff it. Àdiós!
